The season got off to a bad start for the Roadrunners as they conceded five goals in the first half in a formidable Baylor performance that showed why they are ranked 12th in the country.
It took Baylor just three minutes to open the scoring as Vic Hoffman received Bri Campos' pass on the right and was able to chip freshman keeper Katherine Tesno.
In the eighth minute Baylor doubled their lead as Hoffman looked to score again but this time Tesno saved well only for Ashley York to tap home the rebound.
UTSA did manage to have a corner in the 15th minute but it was only temporary respite as another rebound saw Kat Luclow make it three for the Bears.
Soon enough Baylor made it four after a poor pass allowed Alex Klein to take possession and find Natalie Huggins in the box allowing her to score the fourth of the night.
UTSA did manage to get back in to a tight midfield contest but that was only temporary respite as Balyor made it five in the 35th minute with Campos putting away Justine Hovden's cross for the fifth before half-time.
The Roadrunners got some control back and had a chance in the 37th minute from Charlotte Husoe whose effort was saved by Michelle Kloss allowing Baylor to head to the break 5-0 up.
UTSA got off to a much better start in the second half with a Laylla Da Cruz shot going just wide of the post after Baylor had some half chances to start the half.
Baylor just looked content to control possession but the number of subs broke up the game and allowed UTSA to get some shots away with Da Cruz looking the most likely but struggling to hit the target agains some tight defense.
In truth though, Baylor were always in control and UTSA couldn't close the gap as Baylor nearly made it six as they hit the post but had to be content with a 5-0 win.
